Boot into safe mode with a command prompt, then chkdsk /f in the cmd. This will replace/erase any broken data (CAUTION:Might erase some personal data!). ntoskrnl.exe bsod might be caused by a broken boot.ini file, so it should fix that.

It is better not to use (scheduled) sleep and/or hibernate options, but purely on / off computer...until you solve an issue with BSOD...

First, your computer may not ever fall asleep without you, like this, follows this path :
Choose what the power button do;
Change/Create a power plan;
Choose when to turn off the display;
Choose when computer sleeps;

I looked at the list of your BSOD, beep.sys example, can occur when the OS tries to close the active application to shut down the computer, or when lifting OS and run applications takes too long. So I explained that you have just a few active programs in the background...

After a BSOD, turn on or restart the computer, press and keep tapping the F8 key about every second (boot into Advanced Boot Options) until you see the Last Known Good Configuration option. This should start Windows with the last known registry and driver options that worked.

Try these setups and report us the results.Edited by Pionir - 9/15/13 at 4:57pm

After this just push the DRAM frequency from 1333 up to 1600 (save,exit,cpu-z : 800 etc).
Now it becomes a thorny
Your DRAM is not 1866MHz, it is SPD Speed 1333/SPD Latency 9-9-9-24 .It means that 1866MHz you have to achieved through overclocking Warning: Spoiler!(Click to show)

DRAM SPD Speed=default boot.
SPD is a memory hardware feature that makes it possible for the computer to know what memory is present, and what timings to use to access the memory.
For example,G.Skill F3-2400C9D-8GTXD have a SPD Speed = 1600 MHz.

Now, when all this we know, push the DRAM frequency from 1600 up to 1866 MHz, save and exit.

After this you should see your actual (REAL) latency of the DRAM, CPU-Z/Memory...

Note ;
If you elevate the RAM frequency (ex.1866), the less will be the clock speed of the CPU.
So, if you plan to overclock your processor, return back RAM to 1333 MHz - 9-9-9-24 (bios default).
